Type species: Euseboides plagiatus Gahan, 1893 .

Redescription. Body covered with brown pubescence. Pronotum faintly covered with several longitudinal yellowish brown stripes. Elytra covered with spots.

Body small and elongate. Head nearly as broad as apex of prothorax, mandibles bifurcate apically, with an external depression at apex and base; labrum, frons and vertex punctured; frons constricted by eyes; eyes coarsely faceted and strongly emarginate, lower eye lobes small but longer than broad; head with a shallow depression between antennal tubercles; antennae slender and distinctly longer than body, antennal tubercles widely separated, scape elongate and thicker than antennomeres II-XI, pedicel sub-cylindrical. Prothorax sub-cylindrical and punctured, with a transverse groove at apex and base; disc narrowly margined at apex and base, constricted before and behind middle; prosternum punctured, prosternal process broad apically and lower than procoxae, procoxal cavities closed posteriorly. Elytra broader than prothorax basally, gradually constricted posteriorly and abruptly constricted near apex, truncate apically, marginal angles processed; disc punctured, depressed behind scutellum. Mesosternum and mesanepisternum punctured, mesocoxal cavities open externally to mesepimera. Metasternum elongate and punctured, metanepisternum elongate and narrow. Abdomen sparsely punctured. Legs short, mesotibia with an oblique external preapical groove, metafemora not extending beyond apex of abdominal segment III.

Diagnosis. The genus Euseboides is characterized by the following characters: antennae longer than body, prothorax covered with several longitudinal yellowish brown stripes on dorsal surface; elytra with a depression behind scutellum, abruptly constricted near apex, truncate at apex, marginal angles processed posteriorly. Gahan (1893) mentioned that Euseboides was similar to Nyctimene Thomson, 1857 = Nyctimenius Gressitt, 1951 . Actually, Euseboides Gahan is more similar to Malthonea Thomson, 1864 but differs from latter by antennae not fringed with long pubescence beneath, prothorax without a tubercle or spine at sides.

Distribution. China, India, Japan, Thailand, Vietnam.
